Kutcher, 34, and Kunis, 29, have been friends for more than a decade; they first met back in 1998 on the set of “That ’70s Show.” They played an on-again, off-again couple (Michael Kelso and Jackie) for most of the series, which ran for eight seasons.

The pair was first linked romantically back in March, shortly after the breakdown of Kutcher’s six year marriage to Demi Moore. Kunis was also fresh out of a long relationship with Home Alone star Macaulay Culkin.

The two have spent the past few months denying rumors of romance. In August, the actress told British Elle, “Listen, [Ashton and I] hang out. We’ve known each other for 15 years. We have mutual friends. We’re comfortable with one another. That’s it! There’s no crazy love story, nothing more.”
